With at-sea tracking data on their computers two albatross researchers return from sub-Antarctic Marion Island today

South Africa’s research station at sub-Antarctic Marion Island in the southern Indian Ocean is relieved once a year in April-May.  Returning today on the S.A. Agulhas II are two young researchers who have spent the last 13 months studying albatrosses on the island.

2012 BSc Honours graduates Kim Stevens (University of Cape Town) and Stefan Schoombie (University of KwaZulu-Natal) have been studying Grey-headed Albatrosses Thalassarche chrysostoma and the two sooty albatrosses Phoebetria spp., respectively.

Their two studies have been designed to be comparable.  Utilizing colour-banded birds in long-term monitoring colonies, birds were tracked at sea with back-mounted GPS loggers during three stages in their breeding seasons: early and late incubation and while brooding small chicks.  Deployments were made on 45 Grey-headed, 30 Sooty P. fusca and 15 Light-mantled P. palpebrata Albatrosses.  Return rates with successful downloads were good at 69 out of the 90 devices deployed.  Only a few loggers were lost at sea and some birds had data for more than one foraging trip.

In addition, chick regurgitations and squid beak casts were collected on an ad hoc basis to compare with previous studies made on the island, as will be information gathered daily on incubation shifts.

Kim’s study required overnight stays of up to 15 days at a time in a field hut at aptly-named Grey-headed Albatross Ridge on Marion’s south coast – a good day’s walk from the research station on the islands’ eastern side.  Stefan had it a little easier, with some of his study animals being within an hour's walk of the base, although he needed to use fixed ropes as safety aids when working with the sooties that bred on coastal cliffs.

Both Kim and Stefan will now register for Master’s degrees in the Percy FitzPatrick Institute at the University of Cape Town to write up their research findings.  Albatross research at Marion Island is managed by the Institute’s Director, Peter Ryan, who was also on the 2014 relief – as was ACAP’s Information Officer.

The Agreement on the
Conservation of Albatrosses and Petrels

ACAP is a multilateral agreement which seeks to conserve listed albatrosses, petrels and shearwaters by coordinating international activity to mitigate known threats to their populations.
